Battery-powered ultrasound (US) imaging devices in the form of an on-body patch are promising for next-generation health monitoring. They have the potential to enable impactful applications such as blood-pressure, cardiac, bladder, and respiratory monitoring. Research in this area to date has focused on the realization of patch-based flexible ultrasound transducers, while the significant challenges associated with the required battery-powered miniaturized electronics have remained largely unaddressed.
